Abstract

The invention discloses a photoelectric switching device and an electrical switch cabinet provided with the photoelectric switching device. The photoelectric switching device comprises a mounting base and switching mechanisms, wherein each switching mechanism comprises a mold frame and a switching component installed on the corresponding mold frame, each mold frame comprises a bottom base, middle connecting clamps and a top mold frame body, each bottom base is installed on the mounting base, one end of each connecting clamp is detachably connected to the corresponding bottom base, the other end of each connecting clamp is detachably connected to the corresponding top mold frame body, and the switching components are installed on the top mold frame bodies and / or the connecting clamps; each switching component is an optical switching adapter assembly or an electrical switching insertion core body. The photoelectric switching device is located in the electrical switch cabinet. According to the photoelectric switching device, an optical switching mechanism is clamped and fastened to the mounting base, and optical fiber switching can be rapidly achieved through the optical switching adapter assembly arranged on the first top mold frame body; an electrical switching mechanism is clamped and fastened to the mounting base, and electrical switching can be rapidly achieved through the electrical switching insertion core body.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a photoelectric switching device and an electrical switch cabinet provided with the photoelectric switching device. Background technique [0002] The secondary devices of the switch bays of 10KV and 35KV substations are basically installed on-site, that is, the secondary devices are installed on the switch cabinet door, and the secondary wiring on the back panel of the secondary device is directly connected to the terminal block in the switch cabinet. Affected by the life of electronic components, the normal service life of intelligent relay protection devices is about ten years. The service life of primary substation equipment is usually 25-30 years, so the intelligent relay protection device needs to be updated once or twice during the life cycle of the primary equipment. [0003] Traditionally, when the relay protection device is modified, it is necessary to re-c...
